PEREZ, or NEWPORT BEACH, oanrronirra LAND AND WATER'AEROPLVANE Application iled May 31, 192,8. Serial No. 281,831.

My invention is a land and water aeroplane of a type adapted for propulsion through the water in the'mann'er of a boat.

An object of my invention is the construc-A ing a propeller on the forward or bow end of the fuselage or boat hull and having surmounted on this hull a superstructurewith a second motor in the forward end thereof and'on ltop ofthe superstructure there is a tur'iet with a motor and a propeller mounted on the bow end thereof. l

Another object of my invention is mounting on the boat hull fore and aft monoplane wings arranged in tandem and connected .to the turret or superstructure to provide a pa1r of biplane wings, these wings being tiltable for use in vertical direction of ying.

Another object of my invention is the mounting of a steering rudder on to of the turret, this having a vertical blade which may be turned at var-ious angles to give dlrection horizontally. Y

- Another object of my invention is to form a parachute construction bv swinging an upper Hap of a fore and aft set of wings forwardly and backwardly to engage the biplane wings and form with side plates connected to the outer portion of the wings a parachute structure. Another object of my invention is inthe controls'for the various movable parts of the aeroplane.l

My invention is illustrated in the accompanying drawings in which:

Fig. 1 is a side elevation,

Fig. 2 is a plan,

Fig. 3 is a front elevation,

Fig. 4 is a horizontal section substantially on the line 4-4 of of the hull,

Fig. 5 is a horizontal section substantially on the line 5-5 of Fig. 1 through the super- Fig. 1 of the lower part structure, showing the controls for the parachute flaps,

Fig. 6 is a vertical section on the line 6-6 of Fig. 2 in the direction of the arrows,

through theturret, showing the control for {(:he elevation steering wings and for the rud- 7 is a detail'section on the line 7-7 of Fig. 2 lshowingthe attachment of the para-- chute flaps to the main portion of the wing. The boat hull 11 forms the main structure,

-and'on this there is built a superstructure 12,

and on top of the superstructure there is a turret 13. The hull has a fore and aft deck 14, the superstructure has a deck 15, and the turret has adeck 16.

The hull has a pair of supporting wheels 17 mounted on an axley 18 extending through the hull, andat. the stern has a rudder post 19 with a castor type of wheel 20 on the bottom. The rudder post carries a large rudder 21 for use in steering when traveling in the water and -to act as a vertical fin or as a steering rudder when flying. A water propeller 22 at l the stern of the hull is operated by a motorv 23. There are three propellers 24,25 andA 26 mounted on the front or bow end of the hull 11, the superstructure 12 andthe turret 13 respectively. Each motor hasa separate lengine designated'27'.'

The hull has a forward and rearward set l of wings 28 and 29, these being preferably of a monoplane type and iixedly secured to the hull. Each wing has a parachute flap 30 and 31. The flap 30 on the forward wing is connected to a pintle'pin 32 or other suitable hinge adjacent the trailing edge of the wing,4 and the flap 31 has a hinge connection 33 to the forward edge of the trailing wing. The wing structures have a recess or hollow structure designated as 34 (note'Fig. 7) in which the iaps are housed forordinary iiying. The iiaps are held in flying position by means of nubs 35 engaging in sockets 36, tlenubs being outwardly pressed by springs rection of movement are constructed with a shaft 39 extending through the turret from lside to side and having diagonal bracing 40 A set of control wings- 38 for lvertical di- 4 connected thereto; and attached to this bracing there are wings 41 forming a biplane structure. The shaft 39 has a Worm wheel 42 thereon which may be rotated by a worm 43 on a worm shaft 44, this latter having a hand control wheel 45 (note Fig. 6), this being mounted in the turret. By this construction by rotating the shaft 44 the shaft 39 may be oscillated to change the inclination of the control wings 38 and thus provide for the steering in vertical direction of flying.

The rudder construction for horizontal direction designated 46 is mounted on a vertical shaft 47 extending through the deck 16 of the turret 13; and on the lower end of this shaft there is a worm wheel 48 which meshes with a worm 49 on a control shaft 5() operated by a hand wheel 51 (note Fig. 6). Surrounding the rudder there is a guide cage 52 having a horizontal ring 53 at the top and 54 at the bottom adjacent the deck, with posts 55 extending upwardly from the deck and supporting the ring 53. The rudder has notches 56 to guide the rudder relative to the rings 53 and 54. By this construction it will be seen that by operating the hand wheel 51 the rudder 46 may be turned on a vertical axis.

The control for the rudder 21 comprises a bevel pinion 57 mounted on the rudder post 19 engaging a bevel wheel 58 mounted on the steering shaft 59, this shaft having a suitable control Wheel 60. This control is mounted in the hull 11 and by turning the wheel 60 the rudder 21 may be operated or the castor wheel20 used for steering when on the land. The rudder 21 'may be utilized for steering when traveling on the water or when flying.

The parachute arrangement comprises a pair of triangular, vertical fins or plates 61 which are secured to the ends of the wings 28 and 29, being attached to the rear end of the forward wing 28 and the forward end of the rear wing 29; these fins are preferably attached to the pintles 32 and 33. The apexes of the fins are secured to the ends of the sha-ft 39. A forward set and a rear set of cables 62 and 63 are secured to the forward edge -of the front parachute flaps 30 and the rear parachute flaps 31 respectively. These cables pass through sets of pulley blocks 64 mounted in .the diagonal bracing 40. These cables pass through openings 65 in the turret.

An operatingv drum 66 is mounted on the shaft 67 extending longitudinally in the superstructure 12. This shaft is driven by'a countershaft 68 and positioned either above or below the drum and driving the drum shaft through gears 69. The cables 62 and 63 from each side of the elevator wings 38 pass over sets of pulley blocks 70 and are wound on the drum 66. Therefore by op'- orating the countershaft 68 the drum 66 may be rotated so as to exert attention on the forward and rearwardset of cables 6.2 and 63, which action pulls the front parachute fiap upwardly, pivoting on the rear pintle 32 and the parachute flap 31 also upwardly, the ends of these flaps coming intoengagement with the lower wing of the control wings 38, as shown in dotted lines of Fig. 1. The tension on the cables holds these flaps in place.

The wing structure together with these flaps and the fins 61 act as a parachute in the descent of the aeroplane for landing, the air being in effect caught between the two pockets on each side of the hull of the superstructure. After the aeroplane has landed the flaps may be manually returned to position for fiyinfr by unwinding the cables and allowing the iiaps to be returned to their vproper position in the recesses 34 of the main wing structure. The drum 66 may be held stationary in any desired position by utiliz' ing a pawl to engage the gear' wheel 69 in any suitable manner.

Various changes may be made in the principles of In from the spirit thereof, as set forth in the description, drawings and claims.
